ABSTRACT:
The paper deals with the power quality
analysis of interlaced four quadrants (4Q) converters with constant switching frequency. These are in fact the
input stages of the locomotives and high speed trains supplied by 25 kV, 50 Hz
and 15 kV, 16.7
Hz lines. Due to the high power needed for the train circulation, the 4Q
converters can absorb
distorted currents, whose harmonic content can affect the signaling systems and
communication devices. The presence of more converters gives the opportunity,
using dedicated commutation strategy, to interlace them in order to reduce the
harmonic content in absorbed current. In the paper a suitable model of more 4Q
converters is developed. The control logic implemented in the model allows the
evaluation of the harmonic contribution of both single converter and the interlaced configuration. The analysis is carried out
through electromagnetic transient simulations.
